and the trans-substituted double bond of CJ-15,801 is important for the selective, on-target antiplasmodial effect, while replacement of the carboxyl group is permitted, and, in one case, favored. Additionally, we show that the antiplasmodial potency of CJ-15,801 analogues that retain the R-pantoyl and trans-substituted enamide moieties correlates with inhibition of P. falciparum pantothenate kinase
人类疟疾寄生虫恶性疟原虫的存活取决于泛酸(维生素B 5),泛酸是基本酶辅因子辅酶A的前体。CJ-15,801,泛酸的酰胺类似物,从真菌Seimatosporium sp。分离。先前显示,CL28611可通过靶向泛酸利用来抑制恶性疟原虫的体外增殖。为了告知下一代类似物的设计,我们着手合成和测试了一系列合成的带有酰胺基的泛酸类似物。我们证明了R-泛酰基部分和反式的守恒CJ-15,801的双取代双键对于选择性的靶向抗血浆药物作用很重要,同时允许羧基取代,在一种情况下,这是有利的。此外,我们显示保留R-泛酰基和反式取代的酰胺基部分的CJ-15,801类似物的抗血浆活性与抑制恶性疟原虫泛酸激酶(Pf PanK)催化的泛酸磷酸化相关,暗示与Pf PanK的相互作用为抗疟原虫活性的关键决定因素。
